问答题
The world producer price for baseballs is ＄24 per dozen, and almost all of them are produced outside the U.S. Suppose the U.S demand curve is QD=100,000-2,000P, where P is price per dozen, and Q is measured in dozens. The U. S domestic supply curve is QS=-10,000 + 1,000P. (a) Before a tariff is imposed, what is the U. S equilibrium price? Domestic consumption? Domestic production? Imports? (b)Congress has decided to help the baseball manufacturing industry for national security reasons, and it imposes a tariff of ＄6 per dozen. What are the new equilibrium price, domestic consumption, domestic production, and imports?
【正确答案】
【答案解析】(a)Without a tariff, the domestic equilibrium price is the world price of ＄24.
The domestic consumption equilibrium is
QD(24)=100,000-2,000(24)=52,000. Domestic supply is
QS(24)=-10,000+1,000(24)=14,000, so imports equal 38,000. (b)The
new equilibrium price is 24+6=＄30. After the tariff, domestic demand is
QD(30)= 100,000-2,000(30)=40,000, and domestic supply is
QS(30)=-10,000+1,000(30) = 20,000; imports therefore fall to
20,000.
